leak Detection dye?

Thanks for the info guys ....I have some dye that is used to check for plumbing/sewer leaks that I am going to try ...I have several suspect areas ..cracks in the tile ...ect ....

Most guys I know used food coloring or fountain pen ink or phenol red (the pH test dye). When I've done it, I've mostly used phenol red.

I'd check on the toxicity of plumbing dye before I put it into a pool.

The phenol red from the Taylor 2005 / 2006 testkits works well, and the bottle allows you to inject a fine stream of dye near suspected leaks to see if there is any 'ex-flow'.

The phenol red worked excellent .....found several leaks and patched them with the 2 part dough type expoxy ...seems to have gotten most of it but loosing some level ....Hard to tell with 95* days ...will keep looking and maybe the bucket test ...thanks ....mike

Just make sure that, once you use the Phenol red, to mark the bottle, and not use it for testing water anymore. When you squeeze the bottle, you get the dye. But when you stop squeezing the bottle, it will draw in pool water, diluting the Phenol and will give you skewed readings.

Good reminder Pool Clown. Thanks for thinking to share that.
